Another-ohject-of theinvention is. the pro.- vision of train control-ledmeansafor. operat: ing a signalcprion to the operation-10f; the gates,soz-that-personsapproaching, the crossing will be warned of the approachof. a trainibefore thegates are closed.

Another object of the invention is theprovision of novel means. for.operating the gates, and, for; guiding; said gates during their opening;and closing operations.v

With theaabove and-other obj ects in view, the invention vfurtherincludes the following novel. features and details of construction, tobe. herein-after more fully J described, illustrated. irrtheaccompanying drawings and pointed outin the appended claims.

A conductor 3%) connects one of the contacts 1 with one ofthe motors hi and this motor is eoi'meiiited to the conductor 23" bymeans of a coni'luiftor 4-0.

The conductors or cables justdeseriliied. may be. placed within asuitable conduit or housing such as is illustrated at it in Figure 10 oithe drawings. This housing includes a removable cover ll and is providedupon its interior with sel'iarate channels ll" which receive theconductors, the latter being indicated generally at Ll-1 The contactsP-P are all of like construction and are illustrated in detail in Fignres 5, (5 and 7 of the drawings. They inelude spaced rails l2 whoseends are beveled at 1-3. These rails are connected by substantiallyU-shaped connecting bars M from which they are insulated as indicated atlo.

The rails are adapted to be engaged by a shoe indicated generally at l6in Figure 9 of the drawings so as to bridge the rails and close acirci'iitthrough the motors. One of these shoes may be carried at eachend of the train, or the train may carry a single shoe,

the arrangement ofthe contacts being such that the circuits will becompleted to close the gates before the train reaches the cross ing andto open the gates after the train has passed. The shoe ctnnprises arigid bar all which is carried at the lower end of a right angular arm18 while extending from the arm l? near eaehend thereof are oppositelydisposed headed studs 49. Contact Il'lGJTlbGl'S 50 are movable uponthese studs and are yieldingl y forced outward from the rigid bar 4;? bymeans of springs 51. The leading ends of the members 50 are inturned asshown at 52 so that the shoe inay conveniently enter the space betweenthe rails or contact members The arm 48 is carried by a crosshead 53which operates in vertically disposed guides 54-, the latter extendingdownwardly from one 01 the cars ot the train. a portion of a car isii'idieated at 55 in Figure 5 o't the drawings. The crosshead guides areprovided with a stop Fit-h while the erossl'iead carries an ailjustablestop 53? which is tltltlpll" cd to engage the stop 56 to limit down wardmovement of the shoe it; and by means of which the shoe may beaccurately positioned to engage the contact rails The crosshead 4%. hasconnected thereto one end (it a rod 55% and the tujipositorinl of thisrod is contacted to a pirotally mounted hand lever fill. This lever islocated within the car and carries a spring: a 'tuatei'l hitch indicitedat. (it) which is adapted to engage a toothed segment (3]. l'lyinieratiiu the lever 59, the shoe may be quickly i'i'iored into and outof position to engage the contact rails 42, so that it it desired torender the gates inactive, the shoe may be elevated illJOVG the contact.rails 452.

The operation of the invention is as follows:

It train approaching a. crossing over the track A will tirst have itscontact shoe 4:6 ene aued with the contacts P so as to bridge the.contacts. .Clurrent from the battery S will then flow through theconductor 21 one ol' the contacts l, the comliu'toi'lti, the. coin tacts l. the coiulnctor 20 back to the bat:- tery. As the lamp 238 and hell32 are conneeted in parallel with the contacts through the conductors 27and 29, thelainp will be lighted and the bell operated. At the sametime. a lamp 28 which is connected in the conductor 20 will be lighted,while abell 32 which is included in a shunt; circuit 33' tapped on tothe conductor 20 Will also be operated. As soon as the shoe 46 leavescontacts l, the circuit through the lamps and bells will be broken.Continued movement oi the shoe will bridge the. contacts I, so thatcurrent will flow from one sideofthe tools 1. the conductor 18, themotor M and back to the battery through the conductors 22. The othermotor M is connected. in parallel with the first. mentioned motor bymeans of the conductors l9 and 27. Simuh ta neous operation of themotors hf will thus be etfected and the gates controlled by theseinotors will be moved to a closed position as shown in Figure of thedrawings. After the train passes the crossing, the shoe 46 will engagethe contacts I" and current will flow from one side oi? the battery Sthrough the conductor 21, the conductor 23, to the contacts P throughthe conductor 39 to one of the motors M through the conductor 40 to theconductor 22, the conductor 20 and back to the opposite side of thebattery. The other motor M is connected in parallel with the firstreferred to motor by the conductors 2? and 30. The inotors M will thusbe simultaneously operated to open the gates,

A train moving in an opposite direction along track B will first bridgethe contacts P to operate the signal devices 2828" and 3232 in'themanner previously explained and will thereafter first close a circuitsimultaneously through the motors l 2 to close the gates before thetrain reaches the cross ing and to subsequently close a circuit throughthe motors M and open the gates.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is here-' in reserved tomake such changes as properly fall within the scope of the appendedclaims. Having described the invention what is claimed is 1. In a safetydevice for railway crossings, gates mounted for movement upon oppositesides of the railwaytrack and normally posi-' tione'd at one side of thecrossing, a pair of reversely operating motors associated with eachgate, track contact members positioned upon opposite sides of thecrossing and con nected in circuit with the motors and witha motorsassociated with each gate, one of the I motors of each ga'te'beingconnected in paral lel with a source of current whereby each pair ofgates Wlll be simultaneously moved in a given direction. when a circuitis completed through the motors and train controlled means tosuccessively close and open a pair of gates.

3. In a safety device for railway crossings, a pair of horizontallymovable gates normally located upon opposite sides of the railway trackat each side'of the crossing and adapted to be moved into position toclose the crossing, a pair of reversely operating motors associated witheach gate, one of the motors of each gate being connected in parallelwith a source of current whereby each pair of gates'will besimultaneously moved in a given direction when a circuit is completedthrough the motors, signals also included in circuit with the motor andtrain co-ntr lled means to successively operate the signals and closeand open a pair of gates.

4. In a safety device for railway crossings,

horizontally movable gates located upon opposite sides of a railwaytrack and normally positioned at each side of the crossing, spacedU-shaped rails extending longitudinally upon each side of the track,gate carrying rollers operating within the rails to guide the gates intheir movement, rack bars extending longitudinally of the gates, pinionsengaging the rack bars, reversely rotatable motors for 7 operating thepinions and means to control the motors to move the gates to closed andopen positions.

In testimony whereof I aflix my signature.
